T HE first paper in this series' presented the results of heart disease case finding in the Boston Chest X-Ray Survey for tuberculosis, utilizing 70 mm. photofluorographic films which were read by the survey team for all abnormalities and then reread by a special group of radiologists, working in pairs, solely for abnormalities of the size and shape of the cardiac silhouette. This is a report o...
OBJECTIVE To compare endotracheal tube tip-to-carina distance obtained by ultrasonography vs. that obtained by chest X-ray in neonates. METHODS After endotracheal intubation of 40 neonates, chest X-ray and, within one hour, ultrasonography was obtained for each patient for measurement of endotracheal tube tip-to-carina distance. RESULTS Means of endotracheal tube tip-to-carina distances wer...
This paper presents a method for applying a computer-aided diagnosis (CAD) for pneumoconiosis to chest X-ray images digitalized by the computed radiography (CR) system. When we reported the CAD before, we showed performance of the CAD for chest X-ray images digitalized by a CCD scanner. However, since density distribution of the CR X-ray images is quite different from the images digitalized by ...
conclusions ctr is the most common method of describing the heart size. increased ctr in cxr is associated with poor prognosis, which is suggestive of importance and necessity of early diagnosis. although cxr may not have the same diagnostic accuracy as echocardiography, its easy accessibility and high specificity in diagnosis of cardiomegaly is very helpful, which can play an important and a c...
All patients in 1997 with a histologically proved diagnosis of lung cancer in Castle Hill Hospital in whom a full set of case notes and x rays could be retrieved were studied. All previous chest x rays were reviewed by a consultant chest physician and a radiologist, who were blinded to the eventual site of the lesion and the point at which a suspicious abnormality first appeared. Case notes wer...
background the use of shielding tools and x-ray beam collimator has extensively been advocated as effective methods to reduce radiation exposure to patients underwent radiological procedures. the aim of this study was to address the use of these protection measures during infant chest radiography. material and methods 348digital and/or analogue infant chest radiographs were reviewed that perfor...
INTRODUCTION Computed tomography (CT) scans are often used in the evaluation of patients with blunt trauma. This study identifies the clinical features associated with further diagnostic information obtained on a CT chest scan compared with a standard chest X-ray in patients sustaining blunt trauma to the chest. METHODS A 2-year retrospective survey of 141 patients who attended a Level 1 trau...
For better understanding of pathophysiological aspects of tuberculosis sequelae, we investigated the relationship between pulmonary hemodynamics and chest X-ray findings. One hundred and seven patients with sequelae of pulmonary tuberculosis were examined by the right cardiac catheterization, and pulmonary hemodynamic values were measured and calculated. Chest X-ray findings were defined and cl...
conclusions despite close concordance between ultrasonography and chest radiography, ceus is not a suitable alternative for standard chest radiography in detecting cvc location; however, considering its high sensitivity and acceptable specificity in our study, its usefulness as a triage method for detecting cvc location on a real-time basis in the operating room cannot be ignored. results chest...
A 40-year-old man with a history of hypertrophic cardiomyopathy, progressive dyspnea and refractory ascites was referred to our hospital for heart transplantation. The patient underwent heart transplantation successfully from female donor who died of intracranial hemorrhage. After heart transplantation, the patient recovered uneventfully and discharged 1 month later. By chance, we found a linea...
